NMS is just a genuinely bad game. SFV is a good game with hundreds of retarded issues surrounding it. I think SFV will go down as the biggest "Mess" of 2015. Maybe even this gen , if they dont get their shit together by Season 2.
Broken promises, over-hype, insane fanboys sending death threats to devs/journalists for delaying the game, etc. I don't think it delivered on one promise while lying about a lot of other things. Both games are disaster pieces, IMO.
Maybe this pushes SF5 back on top, but I think NMS got more media play, which is why I think it's a bigger fall than this. Although, SF5 just keeps doing things. Personally, I'm voting SF5, but at one point I was convinced NMS would take it.
